Abstract: In the several preferred embodiments of the present invention disclosed herein, a pneumatic controller is provided with a depending flexible vane which is cooperatively arranged and positioned to be moved in relation to a gas-bleed orifice for selectively regulating the pressure of a gaseous control media being supplied to a pressure-responsive control device. To control the movements of the vane, a variable force is applied to the vane to selectively deflect it in response to variations of a measured condition. Proportional feedback is provided in a unique fashion by supplying the regulated gas to one or more nozzles which are arranged to jet gas against the vane for reestablishing the equilibrium of the vane in accordance with the regulated gas pressure.
